| Mar-23-12 | | Memethecat: Looked like a draw, but now I think I've got a win, the K has to hop-scotch down the ranks avoiding the long DS diagonal, till he gets to the 2nd rank. Black has to keep checking, a change of mind ...Ra8 wont work: Rh8+ K~ Rxa8 & a2/1. a1 wont work either, unless it checks the WK. 79Kd5 Ra5+ 80Ke4 Ra4+ 81Kf3 Ra3+ 82Kg2 wins
blacks other try:
<I wrote all of the above knowing I would have to analyse what would happen if the R came to the middle & checked when I crossed the long diagonal. During that analysis I realised this would give black the chance to get behind the pawn, not good. So I came up with the following, but left the above in place so folk could see my thought process> FINAL ANSWER
79Kd5 Ra5+ 80Kc4 Ra4+ 81Kb3 Ra3+ 82Kc2 Rc3+ 83Kb2 wins. A K fork ***
Sharp intake of breath, but a bit of reading & all is well. Pleased as punch☺ |

| Mar-23-12 | | psmith: At first I thought this was easy. Then I realized that after 79. Kd5 Ra5+ 80. Kc6 Ra6+ 81. Kb7 Ra7+! Black might be able to draw. But I think White can win by heading to c2. 80. Kc4 Ra4+ 81. Kb3 Ra3+ 82. Kc2 Rc3+ (or 82… a1/N+ 83.Kb2) 83. Kb2 and wins. Actually I think this will work even after the above line leading to 81….Ra7+. Maybe this isn’t so hard after all. Or maybe I am all wet. Let’s see. I think it works! |

| Mar-23-12 | | dragon player: The first thing I noticed was that white is in check.
That's not very common in a puzzle. White has only three
moves, so that makes it a little bit easier.
79.Ke5 is no option because of 79...a1(Q). If white
wasn't in check he could promote with mate, so he has
to find a shelter for the checks. He could go to g7 or
to the b-file, or to the second rank. g7 is no option
for the same obvious reason. But I don't see the
difference in going to the b-file or the second rank.
Hang on, I see something. If white goes to the b-file,
black can keep giving check because if white captures
the rook on the a-file, black promotes with check. So white
has to go to the second rank:
79.Kd5
If 79.Kf5 Rc6
79...Ra5+
If 79...Ra8
80.Rh8+ and 81.Rxa8
80.Kc4 Ra4+
81.Kd3 Ra3+
82.Kd2
Hang on, this doesn't work either. Now black can play
82...Rc3!. I really don't get this. What dóes work?
I give up. I really don't know.
Time to check.
-----------
In the game they agreed a draw.
Lets check the kibitzing.
4/5 now. |

 | | numbersguy70: As a paying member, I am quite annoyed by puzzles that have no clear solution in either the moves or the annotations. They are second in annoyance only to posts which consume dozens of lines of page space and contribute little or no value. |
|
| Mar-23-12 | | galdur: I remember this one from years ago. It´s a straightforward win. The king goes to c2 via the white squares. After it picks up the pawn it goes to c8 and the white rook covers any attacks by its counterpart. |

 | | Diademas: Nice job LTJ!
I guess that covers all the bases. |
|
| Mar-23-12 | | Patriot: Material is even.
White is in check and both pawns are one square shy of being queens. If white can avoid checks he will win. And he must avoid walking onto the a1-h8 diagonal or the a-file or h-file to prevent a1=Q+. The only way to win seems to be to use the a-pawn as a shield. So 79.Kf5 looks fine. For example 79...Rf6+ 80.Kg5. But perhaps 79.Kd5 is best since black cannot get behind the c-pawn. I'll go with that. 79.Kd5 Ra5+ (79...Ra8 80.Rh8+ Kd7 81.Rxa8  ) 80.Kc4 Ra4+ 81.Kd3 Ra3+ (81...Rd4+ 82.Ke3 ) 82.Ke2 But I think there are many ways to win this: 79.Kd5, 79.Ke5, or 79.Kf5. The key is staying off the a1-h8 diagonal, avoid perpetual, and use the a2-pawn as a shield on the second rank. But also I would avoid b3 and c2 to avoid promotion to a knight with check. |
|
| Mar-23-12 | | Patriot: Well I believe I goofed on this. 79.Kd5 appears to be the only way to win. |
|
| Mar-23-12 | | Patriot: There's definitely more to this than I thought! 81.Ra3+ Kc2! 82.Rc3+ Kb2! That's the key! |
|
| Mar-23-12 | | MarkFinan: If white can keep his king on the light squares, it seems pretty cut and dried to me! |
|
| Mar-23-12 | | LoveThatJoker: <Diademas> Thank you for the kind words, man. This was a fun puzzle to solve and I'm glad that you found my solution to be correct and comprehensive. Sincerely,

| Mar-23-12 | | Kinghunt: I believe the specific moves aren't important here, so long as white plays to walk his king down towards the a2 pawn while ensuring that the pawn cannot queen with check. (This means that if the rook checks on the a file, it cannot be taken.) Clearly, this requirement means the king cannot go to b2, but it has a haven on c2: the rook cannot check it there from the a file, and if it leaves the a file without a check, white can queen and mate. Black could promote to a knight with check, but then Kb2 and the black rook can't guard against queening and protect the knight at the same time. The white king will then walk back up the board and establish a basic Lucena position. |

| Mar-23-12 | | MarkFinan: <kinghunt> Thats exactly what i meant to say, you just explained it better. :) |

Perhaps Alekhine was giving Bogoljubov a little payback. A few months earlier in the Breyer Memorial in Pistyan, Bogoljubov had won the tournament by edging out Alekhine and Spielmann by 1/2 point. Alekhine had led the tournament by 1/2 point with only three rounds to go, but then he conceded a draw to Spielmann, and later a draw to Reti in the last round, while Bogoljubov was winning the tournament, by winning his last four games. > Alekhine vs Reti, 1922
In Pistany 1922, Alekhine was standing clearly worse in his last round game against Reti. In the final position, AAA could fight on for a draw but had no realistic winning chances. After Bogo won his final game over Euwe, the draw was agreed in AAA-Reti. |

| Mar-24-12 | | zakkzheng: So the answer is a draw,huh? |
|
| Aug-30-13 | | MarkFinan: Should White not win this game?
My engine gives it +3.28 in Whites favour anyway. And it does not like 72...a2? at all! |
|
| Dec-04-14 | | IamVoltaire: According to Gelfer in his "Positional Chess Handbook", this game was won by White. He gives further moves: 79. Kd5 Ra5+ 80. Kc4 Ra4+ 81. Kb3 Ra3+ 82. Kc2 Rc3+ 83. Kb2 1-0 (If 83... Rc1 84. Kxa2). |

 | | Honza Cervenka: Okay, the game was long and exhausting, and most of the time Bogo was struggling for survival. Thomas blundered with 72...a2 (72...Kd8 was necessary) but Bogo did not notice the chance to win the game by return of the King to the Pa2. After all, even the best chess players are just humans. |

In fact white has to be quite precise here to avoid promotion of a-Pawn to the Queen with check, and transfer of the Rook to the c-file. At some points he has alternatives but the finish is still the same: black Rook can reach c-file only then, when white King is close enough to eliminate Pa2. For example, if white would have continued with 79. Kd5 Ra5+ 80. Kc4 Ra4+ 81. Kd3 Ra3+ (81...Rd4+ 82.Kc2! Rc4+ 83.Kb2! doesn't save black) 82. Kd2(?), then now 82...Rc3! draws. |

| Mar-15-18 | | Straclonoor: Final position won for white if we can trust Schredder 6-man TB - 79. Kd5 win in 36 moves, 79.Kf5 gives draw, 79. ke5 loses in 8 moves. |
